Compare the initial trace with the overlaid derivatives. Upper: an arbitrary trace representing the general raw signal data. The x-axis could be assigned with any independent variable, or simply use the index of the point in the data sequence. Bottom: the overlay of the positive part P and the negative part N+ of the derivative. Remark: the overlaid diagram forms a profile similar to the initial trace. The fact inspired the idea of using the two parts of the derivative to reconstruct the signals
